Assign / Unassign a user

As an organization admin, I can assign / unassign someone as a user for a given service

AC

• When selecting a service, a button to assign / unassign is available for each user
  • If user is not assigned: appears on hover, tooltip: "Assign"
  • If user is assigned: shown permanently, tooltip: "Unassign"

• Clicking the button assigns the person to this service if it is not the case yet
  • A confirmation is shown: "User assigned"
  • Button appears in a different way so that I understand that clicking it again will switch the status (e.g. see the lock / unlock in nightly)

• Clicking the button again
  • removes the assignment
  • shows a confirmation: "User unassigned"

• When selected people can't be assigned because not enough seats remain available, an error message is shown:
  • [number] more seats needed to assign these users
